Do not confuse the air conditioning , heating and ventilation your Toyota Rav 4. Heating and air conditioning are mechanisms that allow you to lower or increase the temperature of the air. The first through the heat emitted from the engine, and the other with the help of a liquid refrigerant . Ventilation is all the circuits and mechanisms that will allow the air to reach the interior. The fundamental element will be the kicker which sends air into your automobile. If little or no air is coming in, it's probably a ventilation issue. Thanks to this text, we will discover how ventilation works, in order to better identify concerns and understand how to resolve them.problem-ventilation-Toyota-Rav-4

How does ventilation work on a Toyota Rav 4

The ventilation is primarily used to regenerate the air in the passenger compartment of your Toyota Rav 4. Concerning the blower, it is generally composed of a resistance, a turbine, and an engine. The lower the integral resistance of the circuit, the faster the turbine turns. By turning the knob in the passenger compartment, the resistance is therefore reduced.

Toyota Rav 4: usual ventilation problems

Dirty air ducts

In the event that the ventilation is working but very little air is reaching the interior of your Toyota Rav 4, it is conceivable that these air flaps are blocked. Thanks to a screwdriver flat, it is possible to remove the air shutter valves. It is enough to check inside if they are congested. If this is what happens, it is possible to clean them, as well as the shutters.

Dirty cabin filter

If you ever perceive effluxes and your ventilation is poor, the problem is probably due to the cabin filter of your Toyota Rav 4. The latter clogs and accumulates bacteria as time goes by. It is quite normal that it is clogged, it serves to filter the air which reaches us. There is no instruction from the manufacturer on when to replace it. It is advisable to simply remove it, check its condition. If the latter is totally dirty, it will be preferable to change it.

Resistance of the blower HS

If the buttons of the ventilation of your Toyota Rav 4 do not work, if at all, it is probably due to resistance. The resistance allows you to increase the voltage to amplify the speed of the turbine. Strange operation of your ventilation is probably due to a concern for resistance. This small electronic chip is complicated to troubleshoot. We will have to change it.

HS blower motor

There are two fairly regular concerns on the kicker. The brushes are worn. Over the years, these will deteriorate and produce false contact. The fan can spin very randomly, and even not activate at all. In addition, the concern may arise from bearings of the fan motor. In the event that the ventilation whistles, comparable to rusty mechanics, it is possible that the bearings are lacking in lubrication.
